Earth retaining structures are failing daily in all parts of the world due to lack of proper erosion control. The JET FILTER prevents wall failure/movement by relieving water pressure and allowing drainage while saving time and money on extensive repairs. The purpose of the weep holes is to relieve the hydrostatic (water) pressure that inevitably will be behind the wall. The weep holes should have periodic maintenance performed to ensure that they do not become clogged. Panel seams which have opened up or toe failure of the wall can be an indicator of unrelieved pressure due to clogged or insufficient weep holes. The filter media contained in the JET Filter System is the highly rated Mirafi® Filterweave FW300. This media maintains long-term flow rates in high gradient and dynamic conditions. With its removable cartridge, the filter can be changed and cleaned if needed, from the front side of the earth retaining structure without dredging from behind in order to replace the erosion control fabric.
